* improved filter cutoff calculation by adding support for the
following gig parameters: Cutoff freq (used when no cutoff
controller is defined), Control invert, Minimum cutoff, Velocity
curve and Velocity range. The keyboard tracking now also scales
cutoff frequency, not just resonance.

MaxRAMPos=cachedsamples-(pEngine->MaxSamplesPerCycle<<CONFIG_MAX_PITCH)/pSample->Channels;//TODO: this calculation is too pessimistic and may better be moved to Render() method, so it calculates MaxRAMPos dependent to the current demand of sample points to be rendered (e.g. in case of JACK)
